Gene-edited stem cells: a lasting fix for sickle cell?

NCT ID NCT06155500

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study follows 4 people with sickle cell disease who previously received a one-time treatment of their own gene-edited stem cells (OTQ923). Researchers are checking for delayed side effects, such as new cancers or blood disorders, and measuring how long fetal hemoglobin production lasts. The goal is to see if the treatment remains safe and effective over time.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

OTQ923 (gene-edited stem cells)

What this could lead to

If successful, this could show that a single treatment with gene-edited stem cells provides lasting control of sickle cell disease symptoms.

What could go wrong

This is a very small, early-phase follow-up study with only 4 participants, so results may not apply broadly. Long-term risks like new cancers or blood disorders are still being checked.
